@
(Recirculation): Press to turn
the recirculation mode on or off.
An indicator light comes on when
recirculation is on. When the engine
is turned off, the recirculation mode
automatically turns off and must be
re‐selected when the engine is
turned on again.
This mode recirculates and helps
to quickly cool the air inside the
vehicle. It can be used to prevent
outside air and odors from entering
the vehicle.
The recirculation mode cannot be
used with floor, defog, or defrosting
modes. If recirculation is selected in
these modes, the indicator flashes
three times and turns off. The air
conditioning compressor also comes
on when this mode is activated.
While in recirculation mode the
windows can fog when the weather
is cold and damp. To clear the fog,
select either the defog or defrost
mode and increase the fan speed.
REAR: Press to turn the rear
heating and air conditioning on or
off. See Rear Climate Control
System (Rear Climate Control Only)
on page 8‑7 or Rear Climate
Control System (Rear Climate with
Rear Seat Audio) on page 8‑8.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
<
(Rear Window Defogger):
Press to turn the rear window
defogger on or off. The rear window
defogger stays on for about
10 minutes, before turning off.
The defogger also turns off when
the engine is turned off. Do not drive
the vehicle until all the windows are
clear.
For vehicles with heated outside
rearview mirrors, fog or frost is
cleared from the surface of the
mirror when the rear window defog
button is pressed.
Notice: Do not use a razor blade
or sharp object to clear the inside
rear window. Do not adhere
anything to the defogger grid
lines in the rear glass. These
actions may damage the rear
defogger. Repairs would not be
covered by your warranty.
